Patent number: 11403194Abstract: A multicore processor may include multiple processing cores that were previously designated as active cores and at least one processing core that was previously designated as a functional spare. The processor may include an interface to receive, during operation of the processor in an end-user environment, a request to change the designation of at least one of the processing cores. The processor may be to store, into a desired cores configuration data structure in response to the request, data representing a bitmask that reflects the requested change, and to execute a reset sequence. During the reset sequence, the processor may activate, dependent on the bitmask, a processing core previously designated as a functional spare, or may deactivate, dependent on the bitmask, a processing core previously designated as an active core. The processor may include a predetermined maximum number of active cores and a predetermined minimum number of functional spares.Type: GrantFiled: January 31, 2020Date of Patent: August 2, 2022Assignee: Intel CorporationInventors: Eric J. DeHaemer, Arijit Biswas, Reid J. Riedlinger, Ian M. Steiner

The processor may include a power controller having logic to provide for configurability of power management features of the processor. One such feature enables at least one core to operate at an independent performance state based on a state of a single power domain indicator present in a control register. Other embodiments are described and claimed.Type: GrantFiled: June 27, 2019Date of Patent: February 1, 2022Assignee: Intel CorporationInventors: Malini K. Bhandaru, Eric J. Dehaemer, Scott P.

Publication number: 20210191490Abstract: Methods and apparatus for balancing power between discrete components, such as processing units (e.g., CPUs) and accelerators in a compute node or platform. Power consumption of the compute platform is monitored to detect for conditions under which a threshold (e.g., power supply capacity threshold) is exceeded. In response, the operating frequencies of a processing unit and/or other platform components such as accelerators, are adjusted to reduce the power consumption of the platform to return below the threshold. Power limit biasing hints (scaling weights) are provided to platform components, along with a power violation index, which are used to adjust the operating frequencies of the platform components. Optionally, a processing unit can calculate the power violation index and the scaling weights and directly control the frequencies of itself and platform components. Embodiments of multi-socket platforms are also provided.Type: ApplicationFiled: March 3, 2021Publication date: June 24, 2021Inventors: Phani Kumar KANDULA, Eric J.

Patent number: 10503542Abstract: Work can be migrated between processor cores. For example, a thread causing a heavy load on a first core can be detected. A power control unit can determine to migrate the thread from the first less-efficient core to the second more-efficient core. The power control unit can request that the first core and the second core transition to a low-power state (e.g., a sleep state, a C6 power state, etc.). The first core can transfer its software context to a first core software context storage, halt and quiesce. The second core can halt and quiesce. The software context from the first core software context storage can be transferred to a second core software context storage of the second core. A processing core identifier of the first core can be assigned to the second core. The power control unit can then request the second core to transition to an active state (such as a C0 state).Type: GrantFiled: July 30, 2018Date of Patent: December 10, 2019Assignee: INTEL CORPORATIONInventors: Guy Therien, Guy Sotomayor, Arijit Biswas, Michael D.

Patent number: 10331186Abstract: In an embodiment, a processor comprises: a plurality of cores each to execute instructions; a plurality of thermal sensors, at least one of which is associated with each of the cores; and a power control unit (PCU) coupled to the cores. The PCU includes a thermal control logic to preemptively throttle a first core by a first throttle amount when a temperature of a second core exceeds at least one thermal threshold. Note that this first core may be preemptively throttled independently of a throttling of the second core and may have a temperature of the first core does not exceed any thermal threshold. Other embodiments are described and claimed.Type: GrantFiled: January 9, 2017Date of Patent: June 25, 2019Assignee: Intel CorporationInventors: James S. Ignowski, Matthew M. Bace, Eric J.
